IMPROVEMENT IN sAsH-HoLDERs Een RAinRAp-CRS.

The Schedule referred to in theseLetters Patent and making part of thesame.

We, ADAM LOEFFELHOLZ and ANTON Parnu, of l the city of Milwaukee, in theState'of Wisconsin, have invent-ed certain Improvements on Locks andFasteners for Railroad-Car Window-Sash and Blinds,

of which the following is a specification.

The object of this invention is to provide the sashv of the car with aneconomical and useful lock or fastener, having as a leading feature theready and easy aixing or attaching ofthe sash in the frame, and theready detaching thereof, in addition to the usual features of suchfasteners, of securing the sash, when down or when up, and of holdingthe sash at interme-` mediate points of elevation between the lower andupper partsof the frame and consists in an arrangement of a tumblerhaving a key-hole, in combination with the lift and levers, whereby,when the lift is elevated, the keyhole is exposed, allowing the key tobe pnt in use, and to s0 further withdraw the bolts as to allow of thedetaching of the sash 'or blind.

Explanation of 4the Drawing.

Figure l isa perspective view showing the position of the lock on theblind or sash. l

Figure 2, plan showing grooves for the bolts and notches in the iframefor fthe-ends of the bolts,secnring the blinds or sash in place whenKclosed-or opened.

Figure 3, front plate ofthe lock, with the key, and claspior the ends ofthe bolts, shown by front View and by section.

Figure 4, internal arrangement of the parts.

Figure 5, sectional view, showing kneed bolts and lift.

Figure 6, view of the'back plate of the lock.

Figure 7 section through the center of the lock, with space for thebolts. p I

Figure 8, section showing the ends of the bolts and lift.

Figure 9, section showing .the position of the partsv by action of thelift for raising or lowering the blind or sash.

Figure 10, section showing the position of the parts by action of thekey, which admits ef the removal oi" the sash or blind when so desired.

The. other unnumbered views of parts will readily berecognized as v1ewsof detached pieces or parts.

The letters on the dra-win g refer to the several parts thus.

A, front plate of the lock.

B, back plate of the lock.`

0, lift. l

d, angle-levers, face view.

e, angle-levers, edge view.'-

f, pin for angle-levers,- which levers actuate the bolts g, bolts, kneedat eachend.

h, recess on the inner ends of the bolts for the ends oftheangle-levers.

fi, front side and' section of the tumbler with the key-hole.

k, pin of the tumbler, operatingiin and witlrthe lift.

piece.

m, slot-inzthc lift-piece for the guide-piece. u, key-hole in thetumbler. o, springs for the bolts.

p, grooves in the frame, in which the end of the bolts slide.

r, notchesin the frame holding the sash or blind in,

place, either up or down.

Other-'notches may be at such intermediate pointev thus the sashprblindmay be in conditionfto be raised Y or lowered, and when the pressurefrom the litt-is removed the springs will ,come intoplay and force ontvthe bolts, so that thesash or blind will be held closed or opened, asmay be desired; v

In'order to act still `further upon theholts, so as to relievetheir endsfrom Athe recesses in the frame, and' allow of the detaching'andremovalof thesash or blind.

from the frame, when the-lift` O is fully elevated' the key is inserted,and then, by the action ot the key on the tumbler fi, the bolts aredrawn further inward, f and the ends of the'boltsremoved fromttherecesses.

We are aware that an arrangement of springs and levers, to be actuatedby a .thumb-piece or lifts, or by a key, has been used to operate thebolts of sash-holdgrs, and we therefore do not claim such arrangement;ut-

What we do claim is- An arrangement `of lifts, levers, springs, andbolts, in combination with a tumbler, fi, to be operated upon bya key,for the purpose of allowing the sash to be detached or removed from theframe, substantially as herein recited. v lslhis specification signedlthis 17th day of January,
